Since 1980 the European population of the Willow Tit has dropped by 69% – an estimated loss of several millions individuals. Indicators Grey Partridge belongs to the species contributing to decline in the abundance as well as in the biomass of farmland birds across Europe. During thirty years (1980-2010) its population experienced an estimated loss of several millions individuals. We estimate the numbers of Meadow Pipit dropped by few tens of millions individuals in Europe between 1980 and 2010. The decline represents a 66% reduction of this farmland species’ population in Europe. In this update, we present indicators based on increased number of species. For the first time we were able to include data on Black Grouse, Red-spotted Bluethroat and Red-legged Partridge. The overall pattern of population changes has remained unchanged. The decline of common farmland birds has been pronounced and common forest birds still appear to keep stable. Photo by P. Šaj (birdphoto.cz) Summary e This leaflet presents the combined bird species trends of 148 common bird species based on data collected from 25 European countries, covering the period 1980–2010. e Of the 148 species covered, 41 have increased moderately and 2 strongly, 55 have declined moderately and 2 steeply, while 37 have remained stable. In 11 cases do species’ trends remain uncertain. e 37 species were classified as farmland birds, of which 22 declined, 6 increased, 6 remained stable and trends of 3 were classified as uncertain. e 33 species were classified as forest birds, of which 10 declined, 11 increased, 9 remained stable and trends of 3 were classified as uncertain. e The other 78 species were classified as other common birds, and included generalists and specialists of other habitats. Of these, 25 declined, 26 increased, 22 remained stable and trends of 5 were classified as uncertain. e In addition to species’ trends and indices it is relevant to explore the changes in bird abundance and biomass. The biodiversity loss presented by absolute numbers of individuals and tons of biomass might bring a complementary message not only to researchers but also to the public and policy makers. The wild bird indicators for Europe. The numbers in parentheses show the numbers of species in each indicator. The numbers in italics show the numbers of species in each indicator which are moderately or steeply declining , moderately or strongly increasing , stable — and uncertain ? . For explanation of categories of species’ trend see the table (reverse side of this leaflet). Photo by D. Boucný (birdphoto.cz) The absolute numbers of bird individuals that we have lost in last three decades is alarming. This loss corresponds well with the index of biomass of farmland birds which has more than halved during that period (Voříšek et al. 2010, http://www.bou. org.uk/bouproc-net/lfb3/vorisek-etal. pdf). Even though there are 6 farmland species increasing, such as the Common Whitethroat, their rising Countries contributing their data to PECBMS. The data are derived from annually operated breeding bird surveys in 25 countries, spanning different periods, coordinated through the PECBMS. More than 10 000 volunteer counters took part in the surveys. New development in computation techniques allowed us to use data from multiple schemes within one country (Belgium, Cyprus, France, Germany, Latvia, Netherlands, Norway, Spain, Sweden). For details and methods see http://www.ebcc.info/methods2012.html. numbers cannot compensate for the huge loss of individuals of the declining species. Well known and previously common and abundant species such as Tree Sparrow or Yellowhammer are dissappearing from Europe’s contemporary agriculture landscape. Further investigations to explain possible effect of these biodiversity changes on the ecosystem function and services are needed. Abundance of selected farmland birds in Europe. Legend for Table The quality of outputs may differ species by species. In some cases, the coverage of species’ populations and thus the representativeness of the data may be lower at the beginning of the time series (for information on the time span and the list of countries contributing with their data for individual species, see http://www.ebcc.info/trends2012.html). Furthermore, year to year fluctuations might not always reflect real population change, so we recommend cautious interpretation of year by year changes. Readers should also pay attention to individual species’ legends. Long/short-term trend: change (in %) in an index value between first and last year of a time period. Long/short-term annual change: average percentage change per year. Long-term: 1980–2010, Short-term: 1990–2010. Trend classification: strong increase, moderate increase, — stable, moderate decline, steep decline, ? uncertain.

Population Trends of Common European Breeding Birds 2012 Trend classification Long-term The multiplicative overall slope estimate (trend value) in TRIM is converted into one of the following categories. The category depends on the overall slope, as well as its 95% confidence interval (= slope +/- 1.96 times the standard error of the slope). e Strong increase – increase significantly more than 5% per year (5% would mean a doubling in abundance within 15 years). Criterion: lower limit of confidence interval > 1.05. e Moderate increase – significant increase, but not significantly more than 5% per year. Criterion: 1.00 < lower limit of confidence interval < 1.05. e Stable – no significant increase or decline, and most probable trends are less than 5% per year. Criterion: confidence interval encloses 1.00 but lower limit > 0.95 and upper limit < 1.05. e Uncertain – no significant increase or decline, and unlikely trends are less than 5% per year. Criterion: confidence interval encloses 1.00 but lower limit < 0.95 or upper limit > 1.05. e Moderate decline – significant decline, but not significantly more than 5% per year. Criterion: 0.95 < upper limit of confidence interval < 1.00. e Steep decline – decline significantly more than 5% per year (5% would mean a halving in abundance within 15 years). Criterion: upper limit of confidence interval < 0.95. For more details on species trends, including standard errors, see http://www.ebcc.info/trends2012.html.
